Solvo Index scored 21 pest control companies confirmed to serve the Cape Cod hub, which spans Falmouth, Yarmouth, Sandwich, Mashpee, Dennis, Bourne, Marion, and Osterville. Every company is ranked on the same 6-category rubric used across Solvo Index, none are excluded for thin evidence, each carries a confidence tier so you can weigh the score against how well-documented it is. This is a genuinely thinner public-record market than Boston Metro: no company besides GreenHow reaches HIGH confidence, and several carry unresolved founding-date or address discrepancies, disclosed directly in their profiles below.
GreenHow leads with a Solvo Score of 94.9, the only company in this market with a Verified operating profile. Its Cape Cod page names Falmouth, Yarmouth, Sandwich, Mashpee, Dennis, Bourne, Marion, and Osterville. The Barnstable card uses that Osterville listing. The Hyannis card uses the branch at 100 Independence Drive. The next nine companies below it are ranked on the same 6-category rubric using publicly sourced evidence, all at MEDIUM confidence.
Each service tab ranks companies whose Solvo record includes that service. Wildlife stays off GreenHow's list. Bed bug work on that record is limited to existing customers.
Ten location pages filter this file to the evidence on hand for each place. Osterville and Hyannis are villages of the Town of Barnstable. Barnstable and Hyannis use village names and the Hyannis branch address already in this record, and each page labels that evidence.
No company can pay for a higher Solvo Score or a better position. Every company is measured against the same six-category rubric, then sorted by how well its score can be verified, the same rubric used across every Solvo Index market.
Evidence Completeness, the share of fields we could independently verify rather than leave blank, sets each company's Confidence Tier: HIGH at 90%+, MEDIUM at 70–89%, LOW below 70%. A company with a connected operating system (FieldRoutes, ServiceTitan, or similar) carries a Verified tier above HIGH, since that data can't be edited after the fact. No company in this market besides GreenHow reaches HIGH, a real signal about how thin Cape Cod's public record is, not a scoring error.
A published score never exceeds 97.0, even where the formula computes higher, since a 100.0 reads as fabricated rather than measured. Every ranked company, including #1, is required to carry at least one published weakness, so a perfect-sounding entry doesn't exist by omission.
Badges are single-fact superlatives among these 10, each tied to one sourced number, never a blended score. Not a competition for #1: a company can hold more than one.

Ranked by confidence tier first (Verified, then High, then Medium, then Low), Solvo Score second within each tier. "Rating" shows the Bayesian-adjusted score with total review count in parentheses where calculable; "nominal" means the platform reported a rating with no published review count. Full category breakdown for each company is in its write-up below.
GreenHow is the only company with a Verified operating profile confirmed for Cape Cod: Solvo reads its active customer count, recurring-plan rate, and customer tenure directly from its own connected system rather than a public claim. It runs a real branch office at 100 Independence Drive, Hyannis. Its Cape Cod service-area page (greenhow.com/service-area/cape-cod/) names Falmouth, Yarmouth, Sandwich, Mashpee, Dennis, Bourne, Marion, and Osterville. The Barnstable page uses that Osterville listing.
Strengths: The only Verified profile confirmed for Cape Cod: 4,561 active customers, a 90.1% recurring-plan rate, and 5.3-year average customer tenure, figures no other company here can currently show. Its Cape Cod service-area page names Falmouth, Yarmouth, Sandwich, Mashpee, Dennis, Bourne, Marion, and Osterville.
Weaknesses: Wildlife control sits outside GreenHow's published service list, so the wildlife rankings leave it off. Bed bug work is limited to existing customers, and the bed bug pages state that limit.
Our Take: The Verified profile and the eight towns named on its Cape Cod page make this the clearest #1 in a market where almost every other company's town coverage is thin or unconfirmed.
The longest-tenured company in this market by a wide margin: founded in 1910, with a confirmed Connecticut business license number and explicit coverage of 6 of the 8 hub towns (Falmouth, Yarmouth, Sandwich, Mashpee, Dennis, Bourne).
Strengths: A perfect Track Record score (116 years, consistent across its own site and BBB) and a named, checkable license number (Connecticut Business Number B1116).
Weaknesses: Review sentiment is genuinely mixed per independent sources, alongside mostly favorable ratings, some reviews describe negative experiences, preserved here rather than smoothed into a single blended figure. No dedicated Cape Cod office address was confirmed; its BBB-registered pest-control division is based in Providence, RI, not on Cape Cod itself.
Our Take: A century-plus of real operating history is a genuine strength, but confirm it has a technician actually covering your specific town before assuming a Cape-based presence.
Headquartered in Mashpee, with explicit coverage of 6 of the 8 hub towns (Falmouth, Yarmouth, Sandwich, Mashpee, Dennis, Bourne) and a clean BBB record.
Strengths: Strong confirmed town coverage (6 of 8 hub towns, including its own Mashpee HQ) and a clean BBB A+ status.
Weaknesses: A major unresolved founding-year discrepancy: its own marketing claims "over 45 years" while its BBB registration dates to February 2001, a 20+ year gap. Track Record is scored on the more conservative BBB figure, not the marketing claim. A separate HQ street-address discrepancy also exists between its site and its BBB profile.
Our Take: Strong town coverage and a clean complaint record, but the tenure claim needs a direct source check before taking it at face value.
A termite-focused specialist founded in 1993 by John Jatczak, publishing a specific Massachusetts Pesticide Bureau license number directly on its own site, the second-most-credentialed company in this market.
Strengths: A specific, named Massachusetts pesticide license number (#20346) published directly on-site, plus NPMA membership, one of the best-documented Credentials records in this market.
Weaknesses: No hub town is explicitly confirmed as served beyond a general "South Yarmouth and surrounding areas" description, Yarmouth itself is HQ-adjacent but not credited under the strict-naming rule. As a termite-focused specialist, tick control, wildlife control, and bed bug service are all unconfirmed, and no guarantee, contract, or financing terms could be sourced at all.
Our Take: Genuinely well-documented on licensing and tenure, but confirm town coverage directly, the public record doesn’t name a specific service area.
Family-owned since 1988 and headquartered in Hyannis, with two named trade memberships (NEPMA, NPMA) and a strong, well-documented review base.
Strengths: A large, well-documented review base (288 reviews across platforms) and two named trade-association memberships.
Weaknesses: Local Market Strength stays at 0 on this general ranking, which still uses the September confirmed-towns column. A 2026-10-01 check of fowlerandsonsinc.com/who-are-we names Bourne, Falmouth, Sandwich, Mashpee, Barnstable, Yarmouth, Dennis, and Marion. Wildlife pages use that list. The Hyannis address is the office. A founding-year discrepancy (1988 per site vs. 1986 per BBB) and a street-address discrepancy also exist between its own site and its BBB profile.
Our Take: Strong reputation and tenure. The October 2026 town list is on the wildlife pages. This general ranking still follows the September confirmed-towns column.
A mosquito and tick specialist operating a combined South Shore, Cape Cod, and South Coast franchise territory from Hanover, MA, with a specific, well-defined 7-day money-back guarantee and the highest overall evidence completeness in this market (89%).
Strengths: The most concretely-documented guarantee in this market (a specific 7-day money-back policy plus a matching breakthrough-service retreatment commitment) and the highest overall evidence completeness of any company researched (89%).
Weaknesses: This is a combined multi-region franchise territory run from a single Hanover, MA office on the South Shore, not a dedicated Cape Cod business, Local Market Strength is reduced to reflect the lack of an on-Cape office, and Marion and Osterville are not among its confirmed towns. As a mosquito/tick specialist, termite, wildlife, and bed bug service are all explicitly not offered.
Our Take: Exceptionally well-documented for what it is, a regional mosquito and tick franchise, not a Cape-based general exterminator.
An organic tick and mosquito specialist explicitly confirmed as independent ("not a franchise or large corporation"), with the second-widest confirmed town coverage in this market (7 of 8 hub towns, including Osterville).
Strengths: One of only two companies confirmed for Osterville, with 7 of 8 hub towns explicitly named, one of the strongest town-coverage records in this market.
Weaknesses: A tick/mosquito specialist: termite control is explicitly not offered, and general pest, wildlife, and bed bug service are all unconfirmed. No specific license number is published, only generic "licensed and insured" language.
Our Take: A strong, tightly-scoped local specialist with real Cape-wide reach for tick and mosquito work specifically, not a general exterminator.
Family-owned since 1982 (a founding year consistent across its own site and BBB), headquartered in Harwich.
Strengths: A confirmed, consistent 44-year operating history (1982 founding, matching across site and BBB) and a clean BBB A+ status.
Weaknesses: Review sentiment is genuinely mixed: alongside long-time-customer praise, some reviews describe the phone-answering experience as rude or abrupt, preserved here rather than smoothed into a single 5.0 rating. No hub town is explicitly named despite its Harwich HQ, and no specific pesticide license number is published, only a generic reference to being licensed through the Massachusetts Pesticide Bureau.
Our Take: A long-tenured local operator with a real, documented customer-service inconsistency worth asking about directly.
Headquartered in Hyannis, with a clean BBB A+ status and a confirmed 2006 incorporation date.
Strengths: A clean BBB record and a strong reputation figure, though based on a small, nominally-weighted sample.
Weaknesses: No hub town is explicitly confirmed as served on any page reviewed, despite its Hyannis HQ. Wildlife control and bed bug service are both unconfirmed, and no specific state pesticide license number is published.
Our Take: A clean-record local operator, but confirm town coverage directly since none is published.
Headquartered in West Yarmouth, BBB-accredited since 2011, with a confirmed same-day service and satisfaction/retreatment guarantee.
Strengths: A confirmed satisfaction and retreatment guarantee plus same-day service, among the better-documented Consumer Trust records in this market.
Weaknesses: Despite its West Yarmouth HQ, no hub town, including Yarmouth itself, is explicitly claimed as served beyond generic "all of Cape Cod" language. No specific state license number or named trade certification was found.
Our Take: Solid customer-facing terms, but confirm direct town coverage since none is named on its own site.
The remaining 11 companies researched for this market, including two wildlife specialists and one company with an unresolved corporate-identity concern, appear in the full research index. Town pages above filter the same file.
Every company is scored 0–10 in six weighted categories by a Solvo Index researcher, against fixed written anchors, using only sourced, dated evidence. Category scores are combined into a single Solvo Score (0–100), capped at 97.0. Evidence Completeness, the share of fields independently verified rather than left blank, sets the Confidence Tier: HIGH (90%+), MEDIUM (70–89%), LOW (below 70%). A company with a connected operating system carries a Verified tier above HIGH. Every ranked company, including #1, must carry at least one published weakness.
